Executive Summary

The Essential Addons for Elementor plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its Event Calendar widget. This vulnerability exists in all versions up to and including 6.6.2 because the plugin does not properly sanitize or escape event titles that come from The Events Calendar.
